Management techniques surrounding high tunnel vegetable production are discussed in a new publication from University of Wyoming Extension.

The “High Tunnel Handbook,” B-1234, identifies key parts of high tunnel production and evaluates many frequently asked questions. The 55-page document discusses soil management, growth of various plants in a high tunnel scenario and management of pests and diseases.

Contributor Kelli Belden discusses specific concerns of organic crops in high tunnel beds in the “Organic Production in High Tunnels” portion.

Contributors to the publication include Karen Panter, UW Extension horticulture specialist; Belden, former director of the UW Soil Testing Laboratory; Jeff Edwards, UW Extension pesticide applicator training coordinator and small acre/horticulture specialist; Sandra Frost, UW Extension educator for crops; Axel Garcia y Garcia, UW Extension irrigation specialist; Abdel Mesbah, weed research scientist; and Scott Richard, Wyoming crop producer.

Household greywater provides alternative water source for landscapes

Water drained from baths, showers, washing machines, laundry tubs and bathroom and kitchen sinks, called greywater, can provide a secondary source of water for landscape plants while conserving potable water, according to an educator with University of Wyoming Extension.

“Capturing greywater and using it on your landscape during this summer’s drought may reduce the demand on your potable well water,” said Sandra Frost, based in Park County.

According to Frost, a family of four generates 100 gallons of greywater a day, including warm-up water that could be used on landscape plants.

“Warm-up water is the water you run out of household faucets before the hot water gets to the sink or shower,” said Frost. “Warm-up water is clean, ready to use on your landscape or vegetable garden and has no health issues. Just keep a bucket or container handy and catch it.”

However, she said greywater, not including warm-up water, may contain bacteria, organic matter and other potential pathogens and recommends its use only on landscape plants and not vegetable plants to avoid possible contamination with pathogens.
